This invention has for its object a device for accumulating power and aims to provide a bell or receptacle for compressed fluid which in communication with one or more compressible and closed tubes is adapted to act directly or indirectly upon a shaft, and to be acted upon themselves mechanically or manually, for the purpose that the tubes may expand or increase their volume by the action ofthe compressed iiuid and thereby transmit work to the shaft, and then be contracted or compressed manually or mechanically in forcing the compressed fluid into the bell or receptacle.

Other objects and advantages of the invention will appear as the following description is read in connection with the accompanying drawings.

The accompanying drawings show different forms of the power accumulator.

Figure 1 is a side view,

Figure 1a is a side elevational view of a brake or pawl mechanism for locking the roller.

Figure 4 is a side View, and Figure 5 a top View of a second embodiment. Figure 6 is a plan view of a third embodiment. Figure '7 is a side view, and Figure 8 a vertical section on the line 8 8 of Figure 7 showing a fourth form. Figure 9 is a side view of a modication. Figure 10 is a side View of another modification in expanded position and Figure 11 is a similar View in compressed position. Figures 12, 12a, 13 and 14 show in section details of a tyre.

A bell 1 is in communication with a compressible spiral tube or hose 2 mounted between a lower and an upper disk 3, 4 respectively, the latter offering a passage for two vertical rods or uprights 5 fixed to the lower disc 3 or a stationary base plate. The two discs 3, 4 are each provided with one longitudinal, horizontal rod 6 and 7 respectively, pulleys 8, 9 and 10, 11 respectively being mounted on shafts fixed to both sides of the said rods. A chain, rope or wire 12, runs on the pulleys 8 and 10, the ends of the said chain being fixed to two rollers 14, 15, keyed on shafts 30, 31. Another chain or wire 13 runs on pulleys 9 and 11, and the ends of this chain are xed to two rollers 14', 15', keyed on the same shafts 30, 31 respectively. The roller 14 is provided with a belt pulley 16, which by a chain, belt or the like 17 is connected with a belt pulley 16 on the other roller 15, and by I this both rollers are put in uniform motion when one of them is rotated. This rotation may be effected by means of a crank 32, attached to the roller 14'. Further, a toothed Wheel 18 is attached to the shaft 31 for the roller 15 and meshes with a pinion 19 on a shaft 20. This shaft is the driving shaft in a machine 33 of any convenient type to be driven by the accumulator. 34 designates a Valve in the piping 35 between the bell l and the tube 2.

The power accumulator acts in the following manner:

By the pressure prevailing in the bell 1 and the tube 2 the said tube is kept expanded to its largest volume. Thereby the disc 4 is located at its maximum distance from the disc 3. When the rollers 14' and 14 are then rotated by means of the crank 32 in a counterclockwise direction the rollers 15, 15 too are rotated in the same direction by means of the transmission 16, 17 and the ropes 12, 13 are wound on to the rollers. The disk 4 is thus forced downwards towards the disk 3 for instance into contact with the disk 3, and the tube` 2 being thus compressed. The compressed fluid is forced from the tube 2 into the bell l, where the pressure is thus increasing. The roller 14, 14 may be locked in any position by means of a brake or a pawl mechanism 50, as shown in Figure 1a. When the rollers 14, 14 are released the tube 2 expands again and the ropes 12, 13 are unwound from the rollers 14, 14', 15, 15 which are thereby put in motion (but now in a direction opposite to the former one) the said motion being then transmitted to the shaft 20 by the pinion 19.

Thereby the power accumulator acts as a spring would work for driving the driving or transmitting shaft 20, the motion of which may be controlled in known manner by a suitable governor.

Figures 4 and 5 show a second form where a single central upright 5 is substituted for the two uprights 5 and the rods 6, 7 are ring-shaped. The pulleys 9, 11 are arranged on the ringshaped rods 6, 7 and two lines 13 run on the pulleys 9, 11 in a semi-circular way. The one end of each rope is fixed to a hook 36 and the other end rolled on the rollers 37., or 38. Pulleys 8, 10 may also be used together with rollers 39, 40 and hooks 41. This form in which the operating manner is similar to that described above allows a considerably increased number of pulleys to be provided for facilitating the compressing or charging work.

Figure 6 is a plan view of a third form which differs from the preceding one only thereby that the disks 3, 4 and the rods 6, '7 are elliptical.

Figure 7 is a side View and Figure 8 a vertical section on the line VIII- VIII of Figure 7 showing a fourth form where a iiexible tube 42 extending from the bell l opens into a greater number of compressible, superposed tubes 2 provided between the discs 3, 4. For this reason the pulleys are mounted outside the tubes and in each set they are in staggered relation to one another.

Figure 9 shows the spiral tube 2 mounted between the discs 3, 4 as in Figures 1 to 6, but there is only a single pair of pulleys 21 whose spindle 22 is mounted in a frame 23 guided in a vertical rod 24 with a longitudinal guide 25 for the shaft 22. Each pulley 21 is actuated by a single rope 0r wire 26 whose one end is xed to a roller 43 and its other end is attached to another suitable point 44 of the accumulator. In this figure a metallic spiral is inserted in the tube 2 as a reinforcement.

Figures 10 and 11 show the tube 2 in expanded and compressed position respectively. I-Iereby the spiral tube 2 is mounted between the discs 3 and 4 as in Figure 9, but there are two pulleys 21 instead of one. The spindle 22 of said pulleys is mounted in a frame 23 in the same way as in Figure 9. Each pulley 21 has a rope or wire 26 whose one end is xed to a suitable point 44 0f the accumulator and its other end is fixed to a roller 43.

Figures 12, 12a, 13 and 14 show in section a tyre 27 surrounding the tube 2. In Figure 12 a metallic spiral 28 is inserted between the tube 2 and said tyre 2'7 in order to reinforce the tube 2. According to Figure 12a said spiral 28 is embedded in the tyre 27 in and for the same purpose as in Figure 12. In Figure 13 the metallic spiral 28 is also inserted between the tube 2 and the tyre 27. Said tyre is, however, elongated and provided with a clamp member 60 for jamming the tyre against the tube 2.- In Figure 14 the metallic spiral 28 is laid within the tube 2.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:
